Thalia III

Queen Thalia III Alexandrina Victoria Irene-Aquitania, also known as Thalia Alexandrina Graceling, and colloquially known as Princess in her youth (due to her regal aura), is the reigning Queen of the desolate Kingdom of Phantoms, which includes the Shore of Phantoms, the Screaming Shore, the Vault of Bones, the Island of Skeletons, and the Weeping Vault. She is the older twin sister of Philip (her younger twin brother), who mysteriously vanished into thin air - this left her as the sole ruler. The eldest child and only daughter of the disgraced Prince Joffrey, Duke of the Lands of Doom (who was executed on several acts of High Treason), and the disgraced Princess Elisabeth, Duchess consort of the Lands of Doom (who was married off to another man) - with the loss of her younger twin brother (Philip), her emotionally-distanced response for Elizabeth III (one of her Kingdom`s closest allies) to adopt her younger brother (Prince Thomas), was that he could grow up as a normal child; this decision caused a shockwave to spread through the Kingdom. Consequently, after subgating Avalon to harsh trading restrictions after many wars fighting them, Thalia has risen in popularity and become one of the most rulers of the Mythical Nation Alliance. She is the alternate universe version of the tyrannical Empress Thalia of Greece and Denmark, who had become the Empress consort of the Greek-Denmark Empire; the alternate universe version of Grand Duchess Thalia Elisabeth of Earth 1789, who had been born in December 2, 1789. She is one of the past versions of Empress Thalia of Earth and Mars - making it possible for Thalia to become a Empress consort, a Grand Duchess, or a Empress of Earth and Mars.

Background
Princess Thalia is the eldest daughter and former heir apparent of Prince Joffrey of the Winian Empire, Duke of the Lands of Doom, by his wife Princess Elisabeth of the Imperial Winian-based Kocho Family, Duchess consort of the Lands of Doom. For hundreds of centuries, the Imperial House of Irene-Aquitania had ruled in various countries - holding a reputation for sister/sister, brother/brother, sister/brother, first-cousin, second-cousin, and third-cousin marriages (to such a high extent), that even the experts warned that due to their heavy intermarriages - their gene pool was steadily shrinking year-by-year. Her father was directly descended from the founder and first head of the House itself, Empress Eleanor III of Irene.
